"I bought an 8, as this is my usual size for casual shoes of this type, but they were slightly big. I own the same shoe in a beige/nude color that I purchased 2-3 years ago.. they are an 8 1/2 and fit snugger than these. I sewed a few switches over the elastic bands in the back of the shoe, and now they are perfect. Love the color, and they're comfy. Great for sprucing up a casual/plain daytime outfit!"
